After getting several requests from people who wanted to see what I would do to update the "Ghost Sniffer" I decided it was about time to tackle this project. The Sniffer as seen in the first Ghostbusters is actually a Bacharach air testing device and since finding these are difficult I decided to try something different for the main body: a large toner cartridge. The wand is from a medical suction device (never used) and an old TV antenna. The bulb is from a blood pressure cuff and the shoulder strap is from a Panasonic VHS camera. There is one static blue LED, a color changing LED next to it, two red LEDs at the bottom, and a bright white LED at the end of the wand. The end result is lightweight, fun to use, and fits is perfectly with our other gear.
